INTERVIEWER: But what are the reasons behind keeping the site ad-free and making it clean enough for kids to view?

...

MIKE: It's really just more of our style, too. It wasn't a super hard decision to make. We probably would have been doing it like this anyway. We've always leaned toward the more subtle type of humor, as opposed to over-the-top.

MATT: But when we get our sketch comedy show, dude, there's going to be so many swears!

Even given this attitude, there have been many examples of various degrees of swearing on the website, both stated and implied.

Hairstyle Runner — Three heads in the gallery are titled "smartass" (a swear in and of itself), "mother frig" (substitute for "mother fuck"), and "bad motivator finger" (referring to the middle finger).

This is most likely also a reference to the '90s grunge band Soundgarden's third album, Badmotorfinger, as well as the "bad motivator" possessed by an R2 unit in Star Wars.

Second and Third Games Menu — The titlebar for both pages reads, in part, "for the whole damn family!". Also, on the Second Games Menu, the description for the Homestar Talker reads, "Homestar says the darndest things. You want to make him swear don't you? Shame on you. Call your mother."

Email sugarbob — One of Strong Bad's instant messages contains the word "lmao", which means "laughing my ass off". Another one reads, "SB is the shizzle", which in this context means "Strong Bad is the shit".

Email sb_email 22 — Strong Bad edits the phrase "Thank You" to "Nevermind the Bullocks", a misspelling of a British slang term that can either mean testicles or nonsense (similar to the American English "bullshit").

Email comic — In an Easter egg, one of the records visibly displays the phrase "You Stupid Asshole" (a single by the band Mudhoney). This was later censored in strongbad_email.exe, but remains uncensored on homestarrunner.com.

Email cheat talk — In an Easter egg, an announcer translates one of The Cheat's phrases as "Check it out, this is going to be great. Just say 'Screw all y'all!'" (a direct reference to sb_email 22), then adds "And now on to Lesson 2: All the swears." The record is cut short before the second lesson begins.

While in Trogdor's lair, typing "talk trogdor" when Trogdor is asleep yields the response, "You yell some choice expletives at Trogdor but he doesn't wake up. There's a cool echo, though."

Marzipan's Answering Machine Version 11.2 — Thinking that he had been given the cold shoulder after asking for a seven-letter word, Homestar asks for a four-letter word for censoring a cuss word, which ends up being "beep".

Reynold attempts to "swear a cuss", then says "diaper biscuits", causing the rest of the Commandos to laugh at him.

When Reynold says "I might as well go home and get teen pregnant", Gunhaver calls him a "Cheat Cuss-mando".

Email lady fan — Marzipan calls Strong Bad a "horse's twees". Homestar first used the word "twees" to refer to Strong Bad's butt, also calling it "your buttweesimo", so we can surmise that Marzipan meant "horse's ass", a common insult.

In the DVD commentary, the Brothers Chaps speculate on what Pom Pom said and whether he "dropped an F-bomb". They decide he "definitely dropped an S-bomb".

Email 4 branches — When Strong Bad tries to free Homestar from the water cooler, Homestar says, "Stop! Sweet genius, that hurt!" This is a substitution for the phrase "sweet Jesus".

Sbemail 169 Deleted Scene — The abbreviation "WTPF" (What the pfargtl?) is used as a substitute for the abbreviation "WTF" (What the fuck?).

Another play on "WTF" is again seen in email thunder when Strong Bad says "WTC" (What the crap?).

Homestar Ruiner — After The Cheat scolds Strong Bad for kicking him, Strong Bad replies, "Hey, do you kiss your hot mom with that mouth?" However, decompiling the game shows that the supposed swear is "pink boy".

Strong Badia the Free — After the The Cheat shares his opinion on the King of Town, Strong Bad scolds him, saying "I made you a member of the secret sauce police, not a sailor! Where'd you learn to talk like that?" implying he swore (the game's internal files show that he says "I'm saying something that sounds kind of dirty!"). The Cheat then replies, and Strong Bad says, "Yes, war is that word you just said." which is a reference to the saying "War is Hell" (which is indeed what The Cheat says).

Fan Costumes '08 — In the Toons menu, the cartoon is subtitled "They make a COST out of U and ME" (a play on the phrase "When you assume, you make an ASS out of U and ME").
